This invention relates to an apparatus for making and/or utilizingphoto-records. My application Serial Number 88,903, filed July 3, 1936,discloses a system for selecting and indexing records from a series ofrecords in accordance with the indicia appearing on punched-cardscorresponding to certain individual records in said series. The presentinvention is related to the invention disclosed in said application tothe extent that the method and apparatus disclosed therein may be used conjointly with the invention disclosed herein.

It is an object of this invention to provide a photographic machinehaving a pair of adjacent film tracks, a viewing screen, a copyingplaten and a projection printer, together with selective means wherebythe machine may be operated as a camera or projector to makephotographic records on or project images from a film carried in eitherof the iilm tracks on to a sensitized sheet of a projection printer oron to a viewing screen, and in which contact prints may be made from thefilm carried in one of the film tracks upn the lm carried in the otherof the film tracks.

Modern business methods require that record be capable of being filed insmall space, and that they be capable of being referred to and/orreproduced With a minimum loss of time and labor. In/the past businesswas content to let its records accumulate and be flledin their originalform but space limitationsof today demand, more and more, that recordsbe condensed .in form for storage, yet readily available for referenceand reproduction purposes.

The present invention lends itself to the making of micro-photographicrecords of documents,v

In Fig. 1 of the drawings, 50B-A and EBS--B are daylight loading filmmagazines into one a of whicha reel of unexposed film is placed with theaxial opening of said reel engaging the pin 500. The film 513 extendsbetween the reels in the magazines as follows:

From the magazine 50G-A between upper and lowerfguide rolls 5U'l--A and601B. From 'thence it vis threaded over sprockets 508, 509

and 5I l. Then over roll BIB across the aperture'.l M6 over roll BIB-Aover sprockets 5i |-A, 50S-A, and 50B-A, and thence between upper andvlower guide rolls B01-C and 50i-D into film magazine EU8- B andonto thereel therein. The, ends of the lm feed sprockets 609 and E09-A areformed with pulleys BID and Elli-A,

respectively. Magazines IIS-A and IDB-B have 5g associated therewithpulleys l and S34- A, respectively. Pulleys SM and S34-A have mountedthereon or made therewith ratchet wheels S03 and SUS-A, respectively.Pulley SII is urged to rotate by the spring belt SBS mounted on anddriven by pulley SIII. Pulley S04- A is urged to rotate by the springbelt 50S-A driven by pulley SIU-A. Ratchet wheels S33 and SIII-A may beprevented from turning in one direction by pawls S02 and S02-A,respectively. Pawls S02 and SO2-A are urged towards the ratchetsassociated therewith by springs SIII and SSI- A, respectively.

The parts of the machine depicted in Fig. 1 are housed within a casing C(Fig. 2). The sprockets S08, S09, SIIS-A and SDS-A are journaled inbearings mounted in xed relation to the casing C or a frame carriedthereby. Sprockets III and SI I-A are journaled in bearings carried bythe vertically reciprocable member SI2. The vertically reciprocablemember SI2 is restrained from moving in a sidewise direction by guiderods S24-A and S24-'B of which there are two of each extending throughguide holes in said member. The guide rods S24-A and S24-B are mountedon support members S25- A and S25-B, respectively, which in turn aresupported by the housing or a frame within the housing. The

vertically reciprocable member SI2 carries rollers SI5 and SIS-Atogether with the plate containing illm gate or aperture SIS. RollersSIS and SIS-A and the apertured plate 'lying between are adapted to bemoved slightly in a vertical direction with respect to the verticallyreciprocable member SI2. A pair of springs Sil are placed out of linewith the aperture SIS and normally tend to hold the rollers SIS, SIS-Aand the plate containing aperture SIS in its extreme downward positionwith respect to the member SI2.

A ratchet wheel 52I-A is mounted on the shaft with sprocket SUS and aratchet wheel S2I-B is mountedon the shaft and adapted to turn withsprocket 50S-A.

A ratcheting arm or rack member SI3A is mounted pivotally on member SI2by means of the pin S23-A. Ratcheting arm or rack rnember SIS-B ispivotally mounted on member SI2 by means of the pin S23-B. Ratchetingarm or rack member SiS-A is normally urged towards the ratchet wheelS2I-A by means of the spring SIS-A connected between the lower portionof said arm and the member SI2. Ratcheting arm or rack member S I 9-B isnormally urged toward the ratchet wheel S2I-B by means ci a spring 546-8connected between the lower part of said arm and the member SI2. A pawlS20-A 1s pivoted by means of the pin S22A to the housing C. The pawl520-A is normally urged towards the ratchet wheel 52 I-A by means of thespring S45- A connected between the lower portion of said pawl and theframe member C. Pawl S20-B is pivoted by means of the pin S22-B to theframe or casing C. The pawl S20- B is normally urged towards ratchetwheel S2I-B by means of the spring S45-B connected between the lowerpart of said pawl and the frame.

In Figs. 2 and 2-A of the drawing ratcheting arm or rack member SIS-Aand pawl member S20- A are shown in inoperative position whileratcheting arm or rack member SIS--B and pawl S20-B are shown inoperative position. 'I'he pawls and ratcheting arms are put intooperative position or inoperative position by means of the button orcontrol knob S33 fastened to rocker arm S32. Pivoted to one end of therocker arm S32 isa link SII--A which in turn is pivoted to link membersS29-A and S30-A. Link members S23- A and S30-A are provided at theirupper ends with pins S21- A and S26-A one end of which lies within thecurved slot S23-A and the other ends ci which rest against the lowerportion o! pivoted pawl member S20-A and ratcheting arm SI S-A. 'I'heother end of rocker arm S32 is provided with a link'member SII--B oneend oi' which is pivoted thereto. The other end oi' link member SII- Bis pivoted to links S20-B and S23-B. Link members S3-B and S23-B areprovided at their upper ends with pins S26-B and S21-B, one end of whichlies within curved slot S23- B in the frame or housing C, while theother ends thereof engage the lower ends oi ratcheting arm SIS-B andpawl member S22-B. It is thus seen that when the rocker arm S32 isrocked to the left, pawl S20-A and ratcheting arm SIS-A are withdrawn toinoperative position while ratcheting arm SII- B and pawl S20-B arepermitted to engage the ratchet wheel SZI-B. By rotating the button, orcontrol knob S33, in clock-wise 'direction the rocker arm S32 may bemoved to such a position that ratcheting arm SIS-B and pawl member S20-Bmay be put into inoperative position and pawl S20-A and ratcheting armSIl-A may be put into operative position.

K Below and in alignment with aperture SIS (Fig. 2) there is a secondaperture -SI1 provided in a stationary aperture member. A film iscarried across aperture SI1 by means of' sprockets SIG, SI2, SI! and 8H.'I'hese sprockets correspond to sprockets SIII, SI2, SI3 and SIIdisclosed in my application Serial No. 88,903, filed July 3. 1936. Theyare driven by the means set forth insaid application. Below the apertureSI1, and in alignment therewith the casing C is provided with an openingover which condensing lens S40 is adapted to be brought. The. condensinglens SM is mountedin a frame S39 that may be swung into or out o!registry with` the aperture in the casing. Immediately below theaperture SI1 and the opening in the casing C there is a lamp house SIIprovided with a lamp 543, a condensing re ilector SM and a mirror S42mounted at such an angle that the light from the lamp kS43 is reilectedthereby through the condensing lens 540 and thence through the apertureSI1. Above the aperture SIS and in line therewith islens carrying memberS36 carrying objective lens 541. Pivoted to the member 536 is a memberS38 carrying a ruby glass S31 which may be swung into or out ofalignment with the lens 541 and the aperture SIS.l The lens 541 isequipped with any desired focusing arrangement such as the focusingbarrel 53S, and any desired type of electric shutter known to the art.

It may also be understood that, whereas, i'or simplicity, a conventionaltype of lens assembly has been shown, such assembly may include one ofthe many types of electric shutters known to the art. Such a shutter maybe wired into the usual low voltage, light actuating relay circuit inthe usual manner.

The reciprocable frame member SI2 has pivoted thereto pitman arms SISand SIS-A which are pivoted, respectively, to opposite sides oi' themember. The other ends of pitman arms SIB andVSIS-A are attached to bellcranks carried by gears S35-A and S34-B, (Fig. 2A). Gears S34-A andS34-B are mounted on shafts 14S-A and 14S-B, respectively. These gearsare o! the same size and enmeshed. Gear 534vB is driven by gear 668.From the above it will be apparent that, as gears 534-A and 534Brevolve, the frame member 5|2 is caused to be moved up and down.

Immediately above objective lens 541 (Fig. 3) there is provided a lighttight casing 569 which has provided in its uppermost extremities lightreflectors 510-A and 510-B into which are fitted lamps 51|-A and 51|--B.The top of this casing is made fiush with the top vof the machine whichis shown at 512. The top opening of the light-tight casing 569 isprovided with a ground glass viewing screen 513 which is interchangeablewith a clear glass camera platen. At right angles to the light tightcasing 569 there is a second light tight casing 568. This casing has atone end thereof a transparent member 564 behind which sensitized paper548 may be drawn. Sensitized paper 549 is'fed in front of transparentmember 564 from roll 548 over roller 550 between member 564 and member563. Member 563 is provided with an opening 562 in which is carried aladder chain 559 which engages sprockets 556 and 551. Sprocket 551 isrotated by means of a second ladder chain 560 by means of sprocket 555.Sprocket 555 has made integral therewith or mounted on shaft 561therewith pinion 556 which is driven from gear 580. Sprockets 556 and551 rotate feed rollers 55| and 553. These rollers extend through theback member 563 and into contact with the sensitized paper 549. On theopposite sides of the sensitized paper 549 from feed rollers 55| and 553are mounted opposing rolls 552 and 554, respectively. These rolls areheld by tension springs 565 and 566, respectively, against thesensitized paper 549 to keep the paper in firm contact with feed rolls55| and 553. yrespectively. v

At the juncture of light-tight easings 568 and 569 a mirror 515 ispivotally mounted on shaft 514 so that the mirror may be selectivelypositioned with its lower edge in contact with abutment 516 of thecasing 569 or abutment 896 of casing 568. Below the casing 568 thesensitized paper 549 extends through an opening in frame member 638(Fig. 3--A and Fig. 4) to the stacking compartment. The stackingcompartment frame 638 is provided with an opening in the back thereofinto which the sensitized paper sheet receiving drawer 900 is adapted tobe placed. 'I'he sheet receiving drawer is provided with a false bottom662 which is spring-pressed outwardly by a pair of leaf springs 605. Theopen side of the sensitized paper sheet receiving drawer is providedwith a pair of lips 603 and 601, respectively, at the top and bottom ofthe drawer toprevent the tendency of the paper to spring out of thedrawer when a sheet thereof has been moved into the drawer by means ofthe stacking arm 604, which is pivoted at the pin 608 on frame member609. The sensitized paper receiving drawer 900 is provided with alight-tight cover 640 which is shown in Fig. 3`A as being withdrawn fromthe sensitized paper sheet receiving drawer 900.

The cams 6|4-A and 599 are so mounted on shaft 60| that thestacking arm 604 is in the position'shown in the drawings when cam 589is turned to such a position that the cam follower roller 888 is movedagainst spring 591-A to cause the push'rod 881 to bring the knife 898across the aperture in frame member 69| through which the sensitizedpaper 848 cxtends. The cam 8|4-A is so phased with respect to cam 888thatgits dwell engages the cam follower 8|8-A only after the shearingknife 885 has been moved into cutting'position.

The shaft 624 is shown in Fig. 5 together with the means for rotatingshafts and 883 discussed above together with the means for operating thevarious other devices operated therefrom. The shaft 624 is mounted inbearing members 883, 688, 868, 811, 888, 581 and 688. Shaft 624 hasmounted thereon and fixed thereto gear 652 which is driven by worm 66|mounted on the shaft of the motor 688. The terminals 688 and 66| of themotor 668 are connected, respectively, to leads 661 and 886. Lead 6511sconnected to one side of switch 868, the other side of which isconnected to conductor 688. Any appropriate source of potential forenergizing the motor 688 is connected to the conductors 688 and 888 sothat when the switch 658 is closed the motor 688 will drive the shaft624 at an appropriate speed. Loosely mounted on shaft 624 is a gear 868having a hub 61|. The hb 61| is provided with a pin 1|2 extendingtherefrom. Cam 812 is made integral with the hub 61| and adjacent to thecam is a supplemental friction plate 618 between which and the frictionplate 815 attached to the shaft 624 is a friction clutch disc 614. Thegear 668, hub 61|, cam 612 and friction plate 813 are urged by spring616 towards the friction disc member 615 so that the gear 688, etc. isnormally urged to turn with the shaft 624. The gear 888, hub 61|, etc.are normally prevented from rotating with shaft 624 by means of the pin1|2 which normally lies against the stop member`888 (Fig. G). The gear668 engages gear 534--B mounted on shaft 14S-B. Integral with the gearS34-B are a pair of cams 146 and 221. The structure and relation ofthese cams is better shown in Fig. 6. The gear S34-B engages gear S34-Aof like size. The gear 668 has a diameter equal to one half the diameterof gears E34-B and 534-`A. Gears S34-A and E34-B are provided withpitman arms 5|8 and 5|8-A, respectively. This feature of theconstruction has been described above in connection with Figs. 2 and2--A. The shaft 14S-B is journaled in bearing member 669. Friction disc692 is mounted on shaft 624 and turns therewith. Friction disc 694, cam124, cam 883 and collar member 144 are integrally made and looselymounted on shaft 624. Between the members 692 and E94 friction member698 is interposed. The friction disc 684 and the parts made integraltherewith are normally urged towards member 662 by means of the spring685 mounted between the support 686 and the hub of said member, so thatthe elements 684, 124, 883 and 144 normally tend to turn with the shaft626. These members are restrained from turning by the pin affixed tomember 144 by stop member 126 (Fig. 6). Friction disc member 688 ismounted on shaft 624 to turn therewith while friction member 683, cam802, and collar 1|4, which are made integral, are loosely mounted onshaft 624. Between members 686 and 683 friction member 684 is mounted.The spring 686 mounted between the bearing support 681 and the collar ofmember 1|4 normally tends to move the members 683, 882 and 1| 4 to beturned with the shaft 624. These members are prevented from turning withshaft 824 except for certain selected times by the pin 1|8 affixed tomember 1|4. When the pin 1|8 comes into contact with stop member 1|8(Fig. 6) motion of cam 882 is arrested. Bevel gear 818 engages bevelgear 818 mounted on shaft 881 and turns said shaft. Shaft 881 is mountedat right angles to shaft 824 and the apparatus associated with thisshaft is best seen in Fig. 5-A. Shaft 881 is journaled in bearingmembers 888, 888 and 1|8.

The otherterminal of electromagnet 138 is connected to spring contact 133 opposedto spring contact 132. The spring contact 132 is connected by means ofconductor`19| to the battery lead |i. Spring contacts 132 and 133 areconnected by means of conductors 191 and 198, respectively, to terminalsof switch B.

The electro-magnet 198 is provided with a soft iron armature 139 mountedon spring contact 140. When electro-magnet 138 is energized and armature139 is drawn thereagainst, spring contacts 140 and 14| are closed. Thesecontacts are permitted to open by virtue of the spring tension of springcontact 140 when the electromagnet 138 is dee-energized.

Eiectro-magnet 129 has associated therewith an armature 121, which isnormally pushed away, to the position shown in the drawings, from theelectro-magnet 129 by means of the springs 128. The armature r121carries a stop member 128 mounted thereon to cooperate with pin 125mounted on member 144. The member 144ismade integral with cams124 and803. Cam 808 having a dwell 123 and high portion 118 cooperates with camfollower roller 13|, mounted on spring contact member 132. When theroller 13| lies within the dwell 123 of the cam 803 spring contacts 132and 133` are open. These contacts are closed when the high portion ofcam 118 pushes against roller 13|. Cam 124 having a high portion 115 oflimited extent cooperates with cam follower roller 130 mounted onspringcontact 134 opposed to spring contact 135. Contacts 134 and 135are closed only at such times as high portion 115 of cam 124 is inengagement with the roller 130. Thevcams 124 and 803 are so 'mountedwith respect to cach other that contacts 134 and 135 are closed for ashort time after contacts132 and 133 are opened. Spring contact 134 isconnected by means of conductor 135 to one terminal of switchn A theother terminal oi.' which is connected by means of conductor 838 toone'terminal of the The spring contact 135 is connected by means of theconductor 131 to the conductor 181 which is in turn connected to batterylead |5|. Conductor 188 connected to batterylead |50 is connected to oneterminal o1' the electro-magnet 89|. The other terminal oi' theelectro-magnet 89| is connected by means of contact"110. Conductors 195and 198 arecon-v nected to spring contacts 188 and 110, respectively,and to the terminals of switch E.

Electro-magnet 400 is connected by means of leads 8| and |82 to anactuating circuit in accordance with that shown in Fig. of myapplication Serial Number 88,903, and this electromagnet corresponds toelectro-magnet 400 disclosed in said application. The electro-magnet 400is provided with an armature 898 having thereon a latch member 402. Thearmature 898 is normally urged away from the electro-magnet 400 by meansof the springs 40|. Mounted on the electro-magnet armature 898 is a pin180 which engages with and operates in a slot 159 of lever member 151which is pivoted on the pin 158. The electro-magnet 400 is shown in Fig.6 in energized position.

Electro-magnet 89| is provided with an armature 880 normally moved tode-energized position by springs 892. Mounted on armature 890 is a stopmember 809 adapted to engage and hold pin 1 I2 mounted on hub member81|. The hub member 81|, cam 812 and gear 558 are made integral androtate together when the armature 890 and stop member 809 permit the pinmember 1|2 to pass. The cam 812 has a high portion 114 adapted to engagethe cam follower roller 113 mounted on spring contact member 11| toclose a circuit between contacts 11| and 112. In this arrangement thehigh portion 114 is so placed with respect to the pin 1|2 as to permitthe closure oi.' contacts 11| and 112 only at such time as the pin 1 I2is immediately approaching stop member 809. The gear 888 which turnswith cam 812 meshes with and drives gear 534-B. Gear 534-B is of twicethe diameter of gear 888. Gear /534--B is mounted on shaft 145-B andturns cams 145 and 221 mounted on said shaft. The cam 148 is providedwith a high portion 111 which is opposed to the roller 141.

.The cam 221 is provided with a high portion 118 which bears against camfollower rollers 150, 149 and 148 in the order named. Cam followerroller 150 is mounted on spring contact 152 opposed to spring contactSpring 15| is connected to one terminal of the switch F while the otherterminal thereof is connected to one terminal of the switch L. Springcontact 152 is connected to the remainingcontact of switch L and the twoterminals of switch L are connected in the key re-set circuit oi' a keyre-set system similar to 'that disclosed in my application Serial Number.The cam follower roller 149 ismounted on an armature 184 which isnormally moved away u from the electro-magnet by means of the springs186. Mounted on the armature 164 is a stop member 183 adapted to engagewith and hold the pin 180 mounted on cam member 101. The cam member 101turns with shaft 681 only when the armature 184 of electro-magnet 186 ispulled downwardly. Gear 10| mounted on shaft 681 drives gear 100 mountedon shaft 681--A. Shaft 691-A is used to drive the gear 108 (Fig. 5--A)which in turn acts as a drive for the feed and eject rolls of a punchedcard feed and eject assembly familiar to the art.

Cam follower roller 148 is mounted on spring contact 228 opposed tospring contact 226. Spring contact 226 and 228 together with the cam 221correspond to the elements of like number shown on Fig. 10 of myapplication Serial Number 88,903. Spring contact 226 is connected tooneterminal of the switch H-I the other terminal of which is connected tothe conductor 280. Spring contact 228 is connected to conductor 226A.Conductors 22S-A and 280 have connected thereacross a switch 226. Theconductors .226-A and 280 are connected tc a re-set circuit similar tothat disclosed in my application Serial Number 88,903.

Conductor 12| connected to spring contact 110 is connected by way ofconductor 681 to one terminal of the e1ectro-magnet 684 (Fig. 4). The

electro-magnet 634 may be short-circuited by the be permitted to remainopen. With unexposed lm 5I3 loaded in the upper film track as indicatedIn Fig. 1, and with the lever 682, Fig. 2 and Fig. 2-A tilted to such aposition as to make the desired set of ratchets and pawls operative tofeed the iilm from the unexposed reel to the exposed reel and with thedesired document placed face downward on transparent platen 613 (Fig. 3)and with the mirror 616 swung against abutment 686 (Fig. 3), switch E ismomentarily closed allowing a current to flow from the l5 volt mains |60and I6| through leads 161 and 188 and electro-magnet 68|. This allowsthe armature 680 to be attracted against the tension oi springs 682.Stop member 608 is thus permitted to release pin 1|2 permitting the gear668 and cam 612 to make one revolution after which the pin 1I2 againcomes into contact with stop member 808 which is returned to itsoriginal .position after the opening of switch E. Gear 668 which mesheswith gear 684-B is thus permitted to rotate gears 684-A and 684-13 (Fig.2,-A) one-half a revolution. The movement of gears S34-A and 684-28pulls the reciprocable frame member 5I2 (Fig. 2) downward by means ofthe pitman arms 6I6 and 6|6-A as described heretofore. The movementdownward of the reciprocable frame member 6I2 brings lm aperture 6I6(Fig. 2) and the film 6I8 carried thereunder mto registry with theaperture 6I1. Pressure is nlmtained upon the lm by means of the springsAs the reciprocable member 6I2 and included assembly (Fig. 2) movedownward, illm 6I8 is drawn from magazine 60G-A (Fig. 1), by thisdownward movement. Pawl 620-A (Fig. 2) per- 'mits movement of film fromthis direction because of its disengagement with the ratchet teeth onthe ratchet wheel 62I-A. The film is not permitted to be drawn frommagazine 606-B as pawl 620-B is in contact with the teeth on ratchetwheel 62 I-B on sprocket 608-A.

With this first half rotation of gears 584--A and 684-B cam 612 movingwith gear 668 makes one revolution with the downward movement of thereciprocable member 6|2 during which revolution high point 114 of cam612 has contacted roll 118 closing contact 11| and 112 completing acircuit through leads 168 and 180 which furnish current through contacts168 and 164 to electromagnets 1 I8 and 128. The high portions of cams612 and 146 are so phased or arranged that contacts 168 and 164 areclosed during every other closure of contacts 11| and 112. With theenergization of electro-magnets 1 I8 and 128 the armatures 1I1 and l121are attracted and the stop members 1|6 and 126 release pins 1|6 and 126,respectively, permitting members 1|4-and 144 to make one revolution withshaft 624. Member 1|4 in rotating carries with it cam 802 whose highportion 60| closes contact between spring contacts 16| and 162. Closureof these contacts completes a circuit for electro-magnet 168 and thiselectro-magnet energizes, attracting y its armature 686 to close springcontacts 164 and 166. Closure of these contacts completes a circuit forthe energization of lamps 61I-A and 61IB for a period dependent upon thelength of exposure selected by varying the length oi' the high portionof the cam 802. During such time as lamps 61|-A and 61I-B areilluminated the document placed on glass platen 618 (Fig. 3) isilluminated and the light therefrom is picked up by the objective lens641 which casts an image of said document upon the film in the upper nlmtrack whose aperture 6I1 (Fig. 2) is in its extreme downward position.When the dwell of cam 802 arrives opposite the roller 188 the circuitoi' lamps 61I-A and 61|-B is opened and the exposure is complete.Simultaneously with the movement of cam 602 cams 124 and 608 are turnedon shaft 624 with member 144. During this operation, however, the cam608, while it closes contact 182 and 188 and causes electro-magnet 186to be energized, is ineii'ective because switch C is open. However, cam124 just before it returns to its initial position and after contacts16| and 162 have been opened by cam 602 the high portion 116'of cam 124momentarily closes spring contacts 184 and 186. 'I'he closure ofcontacts 184 and y186 for a brief period completes a circuit forelectro-magnet 88| by way of the following circuit: l

Battery lead |6I, conductor 161, conductor 181, contacts 184 and 186,conductor 186, switch A in closed position, conductor 886, switch I inclosed position, conductor 681, conductor 12| to electromagnet 68| andconductor 166 to battery lead |60.

The momentary energization of electromagnet 88| causes its armature tobe again attractedy permitting piny 1 I2 and gear 666 to make a secondrevolution. The second revolution of gear 666 causes gears 664--A and684-B (Fig. 2A) to be turned one-half a revolution thus raising theframe member 6|2 (Fig. 2). When the frame member 6|2 (Fig. 2) is raised,rack member or ratcheting arm 6I8-B turns ratchet 62|-B and sprocket608-A to take up the slack created in the film 6 I8 by the rise ofmember 6I2. With the rotation ofV ratchet wheel 62|B and sprocket606-l-A the pulley 6|0-A (Fig. 1) is rotated and spring belt 50S- Adriven therefrom actuates the film take up arrangement.

During the revolution of gear 666 (Fig. 6) Just above discussed the cam612 rotating therewith is ineffective to complete a further circuit due1.o the fact that at this time cam 148 is in such a position that theroller 141 is within the dwell and contacts 153 and |54 remain openduring this one-half revolution of cam 146.

Cam 221 is ineffective during this operation inasmuch as switches F, Gand H-I are open and the serial closing of contacts 15|. 152 or contacts155, 156 or 226 and 228 is without effect.

A second document may now be placed on the platen 513 (Fig. 3) and theexposure thereof initiated by the momentary closing of switch E (Fig. 6)as above, to reproduce further documents..

The operation of the machine as a reading machine or visual projectorfrom the upper film track will next be described.

In this case the film 5|3 (Fig. 1) is exposed or processed film and itvmay be the film produced after development of the film exposed asabove. No film is in the lower track.

In this case the glass platen 513 (Fig. 3) is replaced by a ground glassor other suitable translucent screen. The processed film is threadedthrough and fed in the same manner as the unexposed film. Automaticindexing in either direction of the film a frame at a time may beaccomplished by rockng the arm 532 to either of its positions asdiscussed above. In this case switch A (Fig. 6) is open and switches B,C and Dare closed. The mirror 515 (Fig. 3) and the switches F, G and H-|remain in the position as discussed above in4 connection with theoperation of the machine as a camera. Switch E is then momentarilyclosed as discussed above. The closure oi switch E causes electro-magnet88| to be energized and gear 668 is then permitted to turn onerevolution thus bringing the upper and lower film apertures together asbefore. Electro-magnet 129 is energized permitting cams 803 and 124 tomake one revolution. This revolution is without effect, however, becauseswitch A is open and switch B in shunt with contacts l132 and 133 isalready closed permitting electro-magnet 138 to energize and closecontacts 140 and 14| to' complete a circuit for the lamp 543. The lamps51 |.A and 51|-B are not illuminated in this operation inasmuch asswitch D is closed preventing the energizatio'n of electro-magnet 1|8,and escape of cam 802. The light from lamp 543 is `reflected upwardly bymirror 542 (Fig. 2) to pass through the condensing lens 540 and on tothe film 5|3 appearing in the frame 5|8 which is now in its downwardposition. The light passing through the film is picked up by the lens541 which casts an image on the viewing platev or ground glass screen513 (Fig. 3).

As switch A is open, contacts 134 and 135 have no effect uponelectro-magnet 88|, thus a projected image may be held on the viewingscreen for as long a time as the operator desires. To proceed to thenext adjacent picture the operator only needs to momentarily closeswitch E thus initiating the second cycle of movement of the iilm feedand indexing mechanism.

The operation of the machine as a reading machine for visual projectionfrom the lower film track will next be described.

In this case the film 5|3 (Fig. 2) is removed from across the aperture5|5 and processed film 891 is threaded over sprockets 6|0, 6|2, 6|3 and6 I4 across the aperture 5 1 of the lower film track. In this operationthe switches .remain the same as when operating the machine as aprojector from the upper film track with the exception the slot 158 ofthe pivoted lever 151 causes the manual closing of switch Eelectro-magnet 89| is that switches F, G and H-I are closed and switchesL, J and 225 (Fig. 6) are open. When a document image on said film hasbeen chosen and indexed by either of the methods described inapplication Serial Number 88,903 and electro- 5 magnet 400 has beende-energized with the stopping of the film, armature 888 is forcedoutward by the tension of springs 40|. The outward motion of armature888 carrying pin 160 operating in 1 0 point of the pivoted lever 151 tostrike against the hinged member 166 while passing, thus exerting forceagainst the hinge 181 closing spring contacts 168 and 110. y

When these contacts are closed electro-magnet 88| is energized by thefollowing circuit:

Battery lead |5|, conductor 181, contacts 188, 110, conductor 12|,electro-magnet 88|, conductor 188 to battery lead |56. The operations ofthe machine from this point on are similar to those described above inconnection withkthe machine operating as a reading machine or visualprojector from the upper iilm track except for certain differencespointed out hereinafter.

The switch E is manually closed for a short interval to cause the secondcycle of operation to take place after the operator has viewed theparticular image that has beenv selected. Upon the again operatedpermitting gear 668 to make anotherrevolution. As gear 668 vmakes onerevolution gear 534-B and cam 221 make one-half revolution. During thissecond half revolution of cam 221 the high portion 116 thereof strikesroll 150 closi-ng contacts 15| and 152 allowing current to pass throughswitch F and past switch L into the key resettingmechanism described indetail in my application Serial Number 88,903. As high portion 116 ofcam 221 continues its rotation it strikes against roll 148 closingcontacts 155 and 156 allowing current to flow through switch G and pastswitch J energizing electro-magnet 185 by way of the vfollowing circuit;battery lead |50, electro-magnet 185, conductor 801, contacts 155 and156, switch Gand battery lead |5I. The energization of electro-magnet185 for a short period of time releases pin 180 from being held by stopmember 183 mounted on the armature 184. of electro-magnet 185. Cam 101.is thus permitted to make one revolution. As the cani 101 rotates thecam Ifollower roller 18| lying in cam slot 118 causes the crank or rod108 to be actuated to feed a second punched card into a punched cardsensing assembly familiar to the art. Y

As high portion 116 on cam 221 continues its rotation it strikes roll148 closing contacts 226 and 228 causing the circuit to be made throughswitch H--l` and past switch 225 into the reset circuit shown in detailin my application Serial Number 88,903.

.As this reset circuit is closed the drive mechanism for film 881 (Fig.2) resumes its operation and continues to operate until another documentis chosen by one of the two methods set forth in application 88,903. Ifit is desired switch B may be opened in the above operation in whichcase the period within which an image is projected onto the viewingscreen 513 (Fig. 3) would be limited to the time that the high portion118 of cam 803 is'exposed to roll 13| controlling the energizaton oflamp 543 as previously described.

The operation of the machine to make contact prints upon the upper filmtrack from a processed film carried in the lower film track will next bedescribed.

The operation of the machine in this case diiiers from the operation ofthe machine as a visual reading projector from the lower film track incertain respects which are set forth below. Processed film (negative orpositive) is carried in the lower film track while unexposed lrn 513 iscarried in the upper film track. In this case the ruby glas 531 is swunginto position to completely cover the aperture of lens 541 in order toexclude iight from above from falling upon the sensitized film in theupper film track.

When a desired frame of the film carried in the lower film track hasbeen selected by the operation outlined above with respect to theselection and indexing of film in the lower film track, with switches B,L, J and 225 open and with switches A, C, D, I, F, G and H-i closedelectromagnet 891 is energized with the de-energization ofelectro-magnet 400 as outlined above in connection with the selection ofa film on the lower film track and gear 668 is permitted to make onerevolution. In making this revolution the film 513 in the upper filmtrack is brought downwardly across the aperture 515 until it lies incontact with the film 891 across aperture 511. When this action istaking place cams 612 and 146 are active jointly to energize the circuitof electro-magnet 129 by way of the'followng connections:

Battery lead 150, conductor 190, switch D, conductor 120, electro-magnet129, conductor 12|, contacts 111 and 112 in closed position, contacts153 and 154 in closed position, conductor 189 back to battery lead 151.The energization of electromagnet 129 releases member 144 and cams 124and 803 and permits them to make one revolution. Cam 803 in rotatingcloses spring contacts 132 and 133 completing a circuit forelectro-magnet 138 by way of the following circuit:

Battery lead 15|, conductor 19|, contacts 132, 133, electro-magnet 138,conductor 192 and to battery lead 150. 'I'he energization ofelectromagnet 138l and the attraction of armature 139 vcloses springcontacts 140 and 141 completing a circuit to the lamp 543 by way oi' thefollowing circuit:

Power lead 110, switch C in closed position, conductor `142, springcontacts 140 and 141 in closed position, lamp 543, and thence to powerlead 111. The lamp 543 remains illuminated during the period that thehigh portion 118 of cam 803 is in contact with roller 131. During thisperiod light from the lamp 543 is reflected by mirror 542 upwardlythrough condensing lens 540 onto the processed film over aperture 511through this lm on to the unexposed film over aperture 516 to expose thesame. As cam 803 revolves the dwell 123 of this cam comes opposite theroller 131 permitting the opening of spring contacts 132 and 133 tode-energize the electro-:magnet 138 thus opening the circuit of Y lamp543 to extinguish the same. A short period after thelamp 543 isextinguished the high portion of the cam 124 comes into opposition withthe roller closing a circuit between spring contacts 134 and 135 tocomplete a circuit for the energization of electro-magnet 891 by way ofthe following circuit:

Battery lead 151, conductor 181, conductor 131, spring contact 135,spring contact 134, conductor 136, switch A in closed position,conductor 636, switch I in closed position, conductor 631, conductor121, electro-magnet 891, conductor 188 back to battery lead 150. 'I'heenergization of electro-magnet 891 for the period that high por tion 115of the cam 124 is pressed against roller 130 permits the pin 112cooperating with stop member 809 mounted on the armature 890 ofelectro-magnet 891 to escape allowing gear 668 to make anotherrevolution. During this revolution of the gear 658 cams 612/ and 146 areinoperative to produce the completion of any circuit. During thisrotation of gear 668 the gears 534--B and S34-A are turned one-half of arevolution moving the reciprocable frame member 512 to its upperposition. During this onehalf of the revolution of gear 534-B, cam 221is rotated one-half of a revolution during which time it first closescontacts 151 and 152 allowing current to pass through switch F which isclosed and past switch L into the key resetting mechanism described indetail in my application Serial Number 88,903.

As the cam 221 continues its rotation, it closes contacts 155 and 155 tocomplete the energizatlon of the circuit of electro-magnet as outlinedheretofore in connection with the projection of a visual image from thelower film track. The energization of electro-magnet 185 1s followed bythe release of the cam member 101 for the purpose hereinbeioredescribed.

As cam 221 is about to complete the last portion of this half revolutionit 'closes contacts 226 and 228 to operate a reset circuit as shown indetail in my application Serial Number 88,903.

The feeding of a second punched card into the machine as described inconnection with my application 88,903 selects a second record from thefilm 891 and indexes it before the aperture 511 thus de-energizingelectro-magnet 400 to initiate the making of a second contact print asdescribed hereinbefore.

The operation of the machine to produce photoprints from the upper filmtrack will now be described. l

The operation of the machine to produce piloto-prints from the upperfilm track is similar to that outlined above in connection with theproiection of visual images from the upper film track with certainexceptions pointed out herein below.

In this case switch I is opened and switch A is closed to permit theautomatic indexing of the film and the sensitized paper. Switches B, G,and H-lare open and switches C and D are closed. Processed film isloaded into the upper film track as set forth above in connection withthe projection of a visual image from the upper film track. The rubyglass 531 is removed from in front of the objective lens 1141, and themirror 515 is swung so that it lies against the abutment 515 (Fig. 3).Switch E is closed manually when it is desired to make a photo printfrom a particular document image. Closure oi switch E causes theenergization of electro-magnet 891 and the release of gear 568 whichmakes one revolution bringing the film 513 across the aperture 516 toits downward position, as set forth'above, at which time electro-magnet128 is energized as disclosed abovepermitting 'cams 124 and 803 to makeone revolution. During the rst portion of the revolution of these camsspring contacts 132 and 133 are closed energizing electro-magnet 138 andcompleting the circuit of lamp 543 as described above. Lamp 543 whenilluminated causes light to be reflected from mirror 542 upwardiythrough condensing lens 540 onto the film 513 across the aperture 516.The light thus transmitted through the film across the aperture 516, isgathered by the objective lens 541 which casts an image of the filmwithin the frame upon the 75 the battery 623.

sensitized paper `549 appearing immediately behind the transparent paperholding platen 564 (FIS. 3).

lI'he sensitized paper 549 is thus exposed to the projected lightgathered by the lens 541 and cast as an image on the sensitized sheetthrough the intermediary of the reflecting mirror 515 above lens 541.When cam 803 (Fig. 6) has turned to such a position that the roller 13|falls within the dwell 123 the lamp 543 is extinguished as above setforth and the exposure of the photo print is complete. After thecompletion of the exposure asdescribed above, cam 115 closes the circuitbetween spring contact 134 and 135 to complete the circuit ofelectro-magnet 834 (Fig. 4) by way of the following circuit:

Battery lead |50, conductor 188, electro-magnet 891, conductor 12|,conductor 831, electro-magnet 634 (Fig. 4) conductor 636 (Fig. 6),switch A in closed position, conductor 138, contacts 134 and 135,conductor 131, conductor 181 and back to battery lead |51. It is thusseen that electromagnets 634 (Fig. 4) and 891 (Fig. 6) are ener-V gizedin series; The energlzation of electro-magnet 891 permits gear 668 tomake a revolution and return the reciprocable frame member 512 and theaperture 516 to its upward position preparatory to the making ofy asecond exposure. The energization of electro-magnet 634 (Fig. 4)attracts the armature 633 withdrawing stop member 632, from the path ofpin 631 mounted on element 581. permitted to make one revolution withshaft 624. The rotation of gear 586 rotates gear 585, shaft 583. gear582, gear 581, gear 580, gear 558 which drives the sprocket 555, ladderchains 560 and 559. The movement of ladder chain 559 corresponding toone revolution of gear 586 rotates the feed rolls 551 and553 (Fig. 3)sufiicient to feed a length of the paper 549 corresponding to the amountof paper exposed. The paper 549 is fed downwardly through a slot inframe member 591, Fig. 4, into the cutting and stacking compartment.Near the completion of the revolution ofgear 586, conductive pin 588comes into contact with spring contact 588- A and completes the circuitfor the energization of electro-magnet 621 by way of the followingcircuit:

Battery 623, lead 626, electro-magnet 621, conductor 825. spring contactB25- A, gear 586, pin

588, and spring contact 588-A back tothe opposite terminal of battery623. For the purpose of simplicity the battery 623 is shown as being aseparate source, however, it is to be understood that the battery orother source of potential connected to leads 150 and 151 may be used inlieu of The energization of electromagnet 821 attracts the armature 628retracting stop member 630 from the path of pin 629 mounted on member618. AMember 618 together with the gear 611 then makes one revolutionwith shaft 624. The rotation of gear 611 causes gear 616 to be turnedone rovlution revolving shaft 60| and cams B14-A and 599. The rotationof cam 599 actuates the cut-oit knife 595 only after an exposure of thesensitized paper 549 has been fed downward Vresponsive to the movementof gear 586. The actuation of the cut-off knife 595 is accomplished bymeans of the cam 599 pushing cam follower roller 598 against the spring591 thus moving rod 591- A and link 593 pivoted to the rod 591-A and thecut-oil knife 595. Subsequent to the movement of cut-off knife 595across the aperture in frame member 59| cam B14- A comes to such aposition that the cam Element 581 and gear 586y are thusV followerroller 813-A falls into the dwell in cam G14- A permitting the cam:follower roller E13- A to be pushed outwardly by spring 619 thusretracting rod G12-A and link G10-A pivoted thereto and to the stackinglever 604 to move the stacking lever to bring the severed sheet'ofexposed paper 549 into the sheet receiving drawer 900. As shaft 601continues to rotate, stacking lever S04 and cut-olf knife 595l areretracted into the position shown, responsive to the movement of thecams 599 and B14- A as the pin member 629 approaches the stop member630. After a number of exposures have been made the paper receivingdrawer 909 may have its cover 640 slid thereof and the same may beremoved and the paper takenv in the light tight drawer 900 to the darkroom for development.

In the operation of the machine just revealed document images may lbereproduced from film traveling in the upper film track by repeatedmanual depression of the switch E.

The operation of the machine vto produce photo-prints from the lowerfilm track will next be described.

In this operation the switches F, G and H-I (Fig. 6) are closed; L, Jand 225 are open, the remaining switches are left'a'sset forth in theoperation of the machine to produce photo prints from the upper filmtrack.. Processed lm is carried on the sprockets 610, 6|2, 6|3 and 614(Fig. 2) and the film 513 in the upper nlm track is removed fromover theaperture 516. When a desired document imagehas been selected as outlinedabove 'in connection with the disclosure of my application 88,903, theelectro-magnet 400 (Fig. 6) is deer-iergized, closing contacts 169 and110 as disclosed hereinbefore and initiating the energization ofelectro-magnet 891. The energization of this electro-magnet permits gear668 to make one revolution and thereby operate electro-magnet 129 tocontrol the illumination of lamp 543 and the subsequent closure ofcontacts 134 and 135 to complete a circuit for electro-magnet 634 (Fig.4) and 891 (Fig. 6), as disclosed above, to make an exposure andautomatically to cut off and stack the piece of sensitized papercontaining said exposure, whereupon the selection of another document byeither of the methods possible causes the cycle to be repeated andanother photo print made. l

For purposes of simplicity a camera projection printer and readingmachine of the xed focus type have been disclosed, however, it will bereadily appreciated that small changes, known to the art, may convertthis camera projection printer and reading machine to the changeablefocus type.

It will be understood that trailers and leaders of blank :film ofdesirable length may be spliced in the beginning and end of each reel oflm to assist in threading the lilm on the various sprockets and toenable the proper alignment of the desired filn image and the apertureto be made.

It is to be further understood that other machines, known to the art,may be connected either directly or indirectly to this machine withresults satisfactory to both. Thus, as disclosed on Fig.

9 of the drawings of myapplication Serial Num-v ber 88,903 a cardpunching machine of a familiar type may be interposed in the countercircuit. inr

such a manner that when a number is set up on the film counter, anelectrical .contact will be established with the corresponding keys ofthe card punch, causing them to punch into the card the number set up inthe lm counter, to autcmatically synchronize the card with itscorresponding document image or picture.

In the above description and drawings certain conventional elements wellknown in the art of mechanics and photography have been omitted for thepurpose of simplicity. It is to be understood, however, that pressurerollers may be usedV in opposition, to any or all of the sprocketsshown, to hold the film taut against the sprockets, and that continuouslight sources may be used instead of interrupting the supply thereto inwhich case it would be necessary to provide the machine with appropriateshutters which are opened at times corresponding to the period that thelamps are illuminated. It is further understood that the varioushand-operated switches, levers, selecting devices, etc. disclosed hereinmay be operated in certain cases by a single lever or switch and thatthe various friction clutches disclosed herein may have substitutedtherefor positively connected clutches that apply no load to the maindriving shaft except when they are being driven thereby and that suchother modifications and changes may be made in the system as are withinthe skill of one-versed in the art, and that the invention herein is notintended to be limited to the specific devices shown but to include thereasonable equivalent thereof.

This invention may be used by or for the Government of the United Statesfor all governmental purposes without the payment of any royaltythereon.
